SECTIONAL BRUSH WITH TIE-BOLT.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed March 8, 1905. Serial No. 249,066.

To (MZ whom t may concer-77,: v

Be it known that I, CHARLES A. FETTERS, a citizen of the United States,residing at 12 West Sixty-sixth street, New York, county of New York,and State of New York, have invented certain new and useful Improvementsin Sectional Brushes with Tie-Bolts, fully described and represented inthe following specification and the accompanying drawings, forming apart of the same.

This invention is a particular form of that shown in my application,Serial No. 230,448, filed October 29, 1904, for patent on a sectionalhair-brush, in which I have claimed a brush vhaving the entirebrush-block divided into longitudinal strips provided each with a row ofbristle-tufts and having removable means for holding the strips in anoperative relation, whereby the entire brush-block is divisible intoseparate strips to facilitate the cleaning of the bristle-tufts. In thatapplication I made specific claim to a strap fitted around the peripheryof the sectional brushblocl to hold the strips together, and in thepresent application I make claim to a bolt eX- tended transverselythrough the several strips for securing them together.

In the drawings, Figure l shows the back or outer side of the sectionalbrush-block; Fig. 2, an end view of the same with rounded tongues tohold the strips in alinement and bristle-tufts upon the several strips.Fig. 3 shows the face of the brush-block with the strips slightlyseparated from one another in the process of removing them from thetie-bolt. Fig. 4 is a cross-section of the strips at the center line ofthe bolt shown in Fig. 3. Fig. 5 is a side view of the swivel-nut beforeit is fianged into the outer strip. Fig. 6 is a side view of aspring-clamp for the end of the bolt, and Fig. 7 is a section on line 77 in Fig. 6 with the end of the bolt inserted in the clamp and a portionof the wooden strip adjacent. Figs. 8, 9, l0, and 1l show modificationsin the form of the alining means upon the edges of the sections.

The invention is shown in the drawings applied to the so-called army andnavy brush, which is destitute of a handle; but the middle section maybe provided With a handle, as described in my former application, SerialNo. 230,448, and the junction of such a handle with the middle strip isindicated by lines Hin Fig. l herein.

The separable strips a are shown provided in Figs. 2 and 8 upon oppositesides with rounded grooves and tongues c and are provided with the rowsof tuft-holes d, in which the bristle-tufts e are fitted, which areshown only in Fig. 2. The sections are shown perforated transversely atthe middle of their length by holes f, and a bolt g is inserted throughthe holes and provided at one end with a head j and at the opposite endwith a screw-thread. The edge section is provided with a swivel-nut z',having a flange 7c upon its outer end, the nut and fiange being fittedto turn in an opening Z, extended through the strip and having acircular enlargement m at its inner end, into which the inner end of thenut is flanged, as shown in Figs. 8 and 4. The nut is formed with anotch 0 upon the outer side for turning the same. When the sections areassembled together upon the bolt, as shown in Fig. 8, the nut can bereadily turned to screw upon the end of the bolt and the sections thuslocked firmly together. The notch o is preferably made to admit the edgeof a ten-cent piece,'so that the nut can be turned for fastening orunfastening without the aid of any special tool.

An alternative locking device for the b olt is shown in Figs. 6 and 7,in which a sheetmetal thimble p is shown with a iiangep upon its outerend and two tongues q slit from its body upon the opposite sides andformed with a transverse indentation to produce internal shoulders fr.The endof the bolt is shown With an annular groove s, and the shouldersupon the tongues are adapted to engage the groove when the sections areall in their operative position, and the outer section a* is pressedupon the end of the bolt, as shown in Fig. 7. The opening in the tuftedstrip is made to fit the body of the thimble tightly, and the strip hasrecesses z." upon the opposite sides of the opening to permit thetongues to press outwardly when the head s of the bolt is crowded pastthe shoulder r. The extreme end of the bolt is tapered to separate thetongues when pressed between them. Any

suitable fastening may be applied to the outer tufted strip to engagethe end of the bolt.'

Figs. 9 to ll show variations in the form of the alining devices forholding the strips in position. Fig. 9shows dovetailed grooves and ribs0, adapted to lock the sections a together positively independent of thebolt and the bolt then serving to prevent their longitudinaldisplacement when in use. Fig.

4 shows single rectangular tongues and grooves b2 c2 upon opposite sidesof the strips;

IOO

but Fig. l0 shows two suoli grooves f and l. A brush having the entirebrush-blockdivided into longitudinal strips provided each with a row ofbristle-tufts, ribs and grooves upon the strips at the opposite edgesfor holding them in alinenient, a locking-bolt extended transverselythrough the strips with head resting upon the strip at one edge, andmeans swiveled in the opposite edge of the strip for engaging the end ofthe bolt.

2. A brush having the entire brush-block divided into longitudinalstrips provided each with a row of bristle-tufts. ribs and grooves uponthe opposite edges of the strips for holding them in alinement, alocking-bolt extended transversely through the strips with head restingupon the strip at one edge, and the nut v1 having collar L upon itsouter end fitted to socket Z in the strip at the opposite edge, andiianged over upon the inner edge of the strip to swivel the nut therein.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

CHARLES A. FETTERS.
